Great Big Roses Fertilizer Booster for Rose & Flower Gardens, 32 Ounce | Organic; For Roses, Flowers, Hydrangeas & Flowering Shrubs; Mix 4 oz per gal water; More Blossoms & Better Root Uptake

I've been gardening for years, and this is hands down the best rose fertilizer I've used. The difference was noticeable within weeks. My roses are covered in blooms, the colors are vibrant, and the foliage is healthy and deep green. The attached photos speak for themselves. I have multiple rose beds, and this fertilizer has helped produce continuous flowering and strong, vigorous growth. Even during the heat, my roses have remained healthy and beautiful. I will absolutely be purchasing this again. If you're looking for a fertilizer that truly delivers results, I highly recommend giving this one a try.

EDIT 5/17/26…PLEASE REFER TO PICTURES 2&3. MY ROSE BUSHES HAVE A TON OF BUDS ON THEM AND IT WAS REALLY NOTICEABLE. THE BUDDING STARTED 2 WEEKS AGO AND I ATTRIBUTE TO GREAT BIG ROSES.

BEFORE I SAY ANYTHING PLEASE LOOK AT THE PICTURES I TOOK, A PICTURE IS WORTH A THOUSAND WORDS ALSO NOT THE DAYS!! IT IS SO EARLY ON IN THE SEASON AND LOOK TO SEE HOW BEAUTIFUL MY ROSES ARE ALREADY. I LIVE IN PA SO ITS REALLY EARLY ON AFTER A REALLY HARSH WINTER. THEY ARE ALREADY BLOOMING. I have read many mentioning or complaining about the price. It is expensive, but it works A THOUSAND PERCENT AND IF YOU LOOK, OTHER FERTILIZERS ARE PRICEY AS WELL, BUT IT IS UNKNOWN AS TO IF YHEY WORK OR NOT. THIS CONCENTRATE MAKES OVER 30 Gallons, SO YOU GET A LOT OF USE OUT OF IT AND IT WORKS AS I KNOW FROM EXPERIENCE. I WOULD HATE TO HAVE WASTED MY MONEY ON ANOTHER BRAND THAT DOES NOT WORK. THIS PRODUCT HAS PROVEN ITSELF OVER AND OVER TO BE EFFECTIVE. THIS IS WHY I SAY TO PURCHASE WITHOUT RESERVATION. I HAVE TRIED SEVERAL FERTILIZERS AND THIS IS THE ONE PRODUCT THAT WORKS AS IS PROMISED. I FEEL AS THOUGH I AM HELPING OTHERS BY SHARING THE INFORMATION I HAVE ABOUT “GREAT BIG ROSES” SO NOBODY WASTES THEIR MONEY ON PRICEY OTHER BRANDS THAT SIMPLY DO NOT WORK. I FOUND THIS PRODUCT THREE YEARS AGO AND MY ROSE BUSHES ARE SIMPLY AMAZING. PEOPLE STOP AND COMMENT ON HOW BIG AND BEAUTIFUL MY ROSE BUSHES ARE, EVEN THE MAILMAN and Trugreen guy! I can ATTRIBUTE ALL THAT AND MORE TO GREAT BIG ROSES. PLEASE SEE THE PICTURE I TOOK OF MY ROSES, BUT REMEMBER ITS ONLY JUNE FIRST AND WE HAD A HARSH WINTER IN PA. DESPITE ALL THAT, YOU CAN SEE ALL THE ROSES!! PLEASE READ ON! MY BUSHES WERE PRETTY SMALL AND PRODUCED ONLY FAIR LOOKING AND ONLY A FAIR AMOUNT OF ROSES. THE FIRST YEAR I USED IT ALL SUMMER AND ( *****NOTE THAT BY THE END OF THE SUMMER, THEY LOOKED SO BIG AND HEALTHY, AND THEY PRODUCED AN ABUNDANCE OF ROSES.*****) I USED IT LAST YEAR AS WELL WITH THE SAME RESULTS. THIS PRODUCT PROVED ITS RELIABLY. THAT US IMPORTANT BECAUSE IT IS DEPENDABLE. YOU DONT KNOW WHAT THE OTHER BRANDS WILL DO, PLUS OTHER FERTILIZERS ARE EXPENSIVE AS WELL. This will be my third year of using GREAT BIG ROSES and my bushes are FULLY IN BLOOM, THEY ARE EXTREMELY LARGE, AND THERE ARE A LOT OF ROSES. SOMETIMES YOU JUST NEED TO SPEND THE MONEY FOR THE BEST PRODUCT THAT PRODUCES PROVEN RESULTS. IT IS WORTH IT. BESIDES, YOU DONT USE A LOT OF CONCENTRATE AT A TIME AND ONCE YOU ESTABLISH YOUR BUSHES, YOU CAN DO WHAT I DO, BACK OFF A BIT AND INCREASE THE TIME INBETWEEN USES! YOU TRULY WONT BE SORRY YOU SPENT THE MONEY BECAUSE YOURE PRACTICALLY GOING TO GUARANTEED BEAUTIFUL ROSE BUSHES. ITS SUPER EASY TO USE AND I AM HAPPY I FOUND THIS PRODUCT AND HAVE HAD THE RESULTS I DID. ITS EARLY ON IN THE SEASON AND JUST LOOK AT A COUPLE OF MY BUSHES ALREADY! See picture! EXCELLENT PRODUCT, EXCELLENT RESULTS, WORTH THE PRICE. YOU WILL NOT BE SORRY!!! A++++

I always use this fertilizer. It is tried and true. Easy to use and always grants me incredible and healthy looking blooms.

My roses are Beautiful. I have never had so many blooms, and NO black spot. It is AMAZING.

Fantastic product, especially for new/baby roses to help their roots get established. Hate the jug and the giant mouth, I always spill some when trying to measure into my watering can. Considering how bloody expensive this stuff is, I cringe every time it happens.

This works however, I've noticed stronger scents from my roses when I use MiracleGro products instead.

After reading what other users reported, I reluctantly ordered this product. After the first application I saw little improvement. A couple of weeks later I made a second application since we were expecting a large rainfall. It was then that I noticed some of the largest blooms ever on some smaller rose bushes, and two or three had more blooms on them than they had all last year. We are experiencing cool weather, and heavy rains about every week, and the roses are growing and producing abundant blooms. I tried it on my small raised bed garden, and those plants are growing taller with loads of blooms. I don't fully understand the ingredients, but can attest to the results. It is pricey, you get what you pay for.

This stuff is legit. I saw amazing growth on my roses. I thought one of my rose bushes were dying. In about 3 weeks I have blooms on it. After dead heading my other bush I have a bunch of new blooms on it.
